Rose plant

ABSTRACT

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent the rose known as &#34;Peer Gynt&#34; and the rose known as &#34;Brazilia&#34; as pollen parent.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are: (1) large high centered blooms with reflexing petals producing a spiral, circular outline upon opening, (2) unusual bicolored flowers with yellow overcast with light red petal tops and yellow reverse with yellow tinting on the light red surface at the petal base, (3) thick petals of unusually good substance, and (4) a very vigorous plant, upright growing and producing long stems. Asexual reproduction by budding of the new variety as performed in Clackamas County, Oreg., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The new and improved rose variety which I have developed is a fine hybrid tea rose of unusual coloring due to different colors of the undersides of the petals than the top sides. This difference produces an attractive shrimp pink tonality upon opening which is especially appealing because of the physical structure of the flowers. The petals reflex so as to produce a spiral, circular outline. Another outstanding feature is that the hybrid tea blooms are borne singly on long cutting stems and the petals are thick and with very good substance. The plant is very vigorous and presents the high centered blooms well on long cutting stems.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Color Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "13C" is plate 13C of the Royal Horticultural Society Color Chart.

I claim:
 1. A new and distinct variety of rose plant of the hybrid tea class, substantially as shown and described, characterized particularly by high centered, attractive bicolored flowers with thick petals and good substance, borne primarily singly and having a spiral, circular outline, and a vigorous, upright growing plant habit, with long stems and large foliage, and of particularly good disease resistance.
